The download for the project file you have a subscription for will appear on the right-hand side of the projects paid. Once you have paid, simply login and go to that page to download the demo application source code.

Yes, that is the file I downloaded - it is a bit confusing as the downloaded file states it is a demo.So I am guessing I can simply drag and drop controls from the demo project file, into my project file, and they will work without displaying any nag screens or MsgBox's ?

Correct. There is no complicated registration. Once you have purchased and downloaded the "Demo" project source, you can copy/paste the classes in to the projects you wish to use them in, and use the "Demo" project for usage examples.

I know you don't offer support for encrypted users, so if there is anyone else out there who can help with the question below:

I have just noticed that when I try to use any of the buttons in a windows project, the icon becomes ghosted with a very slight pixellated surrounding.They look perfect on OS X, but bad on Windows 7 - does anyone know how to correct this, or are the buttons only really meant to be used on OS X?

Probably wont be able to see it in a screenshot as we are talking about 1 pixel ghosting.

I simply tried the default checkbox style button (where the default icon is an empty star, and when clicked, a green tick mark appears).Yes it seems to be a masking problem, but it looks absolutely perfect in OS X.

If you have access to a windows box, simply try a default button and you will see what I mean.
